Trans-Conductance Tube Tester
Information
The Model TV-12 Trans-Conductance Tube Tester was designed to test tubes under dynamic conditions closely resembling the operating conditions of the tube. It performs this function by measuring the plate current of the tube under test while under the direct influence of an in-phase grid voltage applied to the tube. (See Page 9 for a detailed explanation of the unique circuit employed in the Model(TV-12) With its simplified controls, fast-acting roll chart, self-cleaning lever switches and its English reading “Replace-Weak-Good” meter, the Model TV-12 will quickly and efficiently test the ever increasing niimber of tube types used in Radio, TV etc. for quality, shorts, leakage and noise. As an extra service, TRANSISTORS may be tested for quality in a circuit which converts them to their tube equivalents. Simplification of switching and controls has enabled us to present the operating instructions in a simple, easy to understand style. On the following pages, we have illustrated procedures wherever possible. We suggest you study the data and the instrument panel before you attempt to use the instrument. The 10 minutes spent in doing so will be well invested for if you acquire a proper understanding of how this instrument operates, it will become your most frequently used piece of test equipment. Like all better types of tube testers, the Model TV-12 provides the means of making the three basic tube tests. 1. Tests for shorts and leakages 2. Tests for quality (Good-Weak-Bad) 3. Tests for noise An additional tube characteristic, mutual conductance, while not necessary for ordinary servicing work, can be computed from data supplied by the Model TV-12, (See Page 10) It is always best to proceed with the short and leakage test first and then follow through with the quality test. It is advisable to do so because a “shorted” tube would be identified as such when making the short and leakage test. If such a tube were tested for quality first, it could possibly damage the sensitive meter beyond repair.
